DETAILED DESCRIPTION OF THE INVENTION

The present invention is further described below in conjunction withdrawings.

In embodiment 1, as shown in FIG. 1, a bulletproof structure of thepresent invention includes bulletproof bodies 1 and a bulletproofsubstrate 2, wherein the bulletproof bodies are spheres, and a pluralityof bulletproof bodies 1 are uniformly bonded to the bulletproofsubstrate 2 through super glue a; as a production way, the bulletproofsubstrate can be preliminarily coated with super glue, then thebulletproof bodies are uniformly arranged on the super glue, andgenerally after the super glue is completely solidified, the bulletproofbodies can be bonded to the bulletproof substrate; the bulletproofbodies are generally compactly distributed, and about a half of thesphere is exposed out of the super glue; the bulletproof bodies and thebulletproof substrate can also be directly produced into a whole byusing a mold when in production; in the present application, thebulletproof bodies can be made of the existing bulletproof structurematerial and can generally select two kinds of materials: metal materialand nonmetal material, the metal material can use steel and iron, thesurface is made smooth, and the nonmetal material uses ceramics andglass; and the bulletproof substrate can be made of the existingbulletproof structure material such as steel and iron. The spheres onthe surface of the bulletproof substrate are made smooth.

According to the bulletproof structure provided by the invention, whenbullets hit the bulletproof structure, the surfaces are arc-shapedsurfaces, so that after the collision of the bullets, due to the spacearound the arc-shaped surface, the bullets are not supported, and thedirection of the bullets are easily changed towards the outer side afterthe collision, thereby reducing the impact force, and achieving aprotection effect. The bulletproof structure can also be named as aprotection structure, and the application of the bulletproof structureis the same as that of the existing bulletproof structure, for example,the bulletproof structure can be directly made into bulletproof productssuch as riot shields, or the bulletproof substrate can be fixed onparts, requiring the bullet resistance, of car bodies, ship bodies andthe like in a soldering way, a bolt connecting way, a hanging way andthe like, which are not specifically limited herein

In embodiment 2, referring to FIG. 2, as a variant, the bulletproofbodies are hemispheres, the spherical ends of a plurality of bulletproofbodies 1 are uniformly fixed on the bulletproof substrate 2, and thisstructure can be used for resisting bullets with large impact force; andwhen the impact force is large, the hemispherical bulletproof bodies areeasy to separate from the bulletproof substrate, the counterforce canchange the running direction of the bullet, thereby reducing the impactforce. The structure can also be applied to the situation requiring asmooth bulletproof structure.

In embodiment 3, referring to FIG. 3, as a variant, the bulletproofbodies 1 are hemispheres, and the plane ends of a plurality ofbulletproof bodies 1 are uniformly fixed on the bulletproof substrate 2.By adopting the structure, the bottom of the bulletproof body is stable.

In embodiment 4, as a variant, referring to FIG. 4, one end of thebulletproof body 1 is a hemisphere, the other end is a cylinder, and thecylinder is connected to the bulletproof substrate 2. By adopting thestructure, the thickness of the bulletproof structure can beappropriately reduced, and the thickness of the super glue can beincreased, thereby improving the strength of the bulletproof structureand the firmness of the bulletproof bodies.

In embodiment 5, referring to FIG. 5, two ends of the bulletproof body 1are hemispheres, the middle part is a cylinder, and the spherical endsof a plurality of bulletproof bodies 1 are uniformly connected to thebulletproof substrate 2. By adopting the structure, the direction of thebullet can be changed after hitting the bulletproof structure throughthe side surfaces of the cylinders, thereby reducing the impact force,and also increasing the thickness of the bulletproof structure.

In embodiment 6, as a preferred solution, referring to FIG. 6, thebulletproof body 1 includes a fixed part and hemispherical projections12, wherein the fixed part is formed by integrally connecting aplurality of hollow elastic truncated-cone-shaped projections 11, theupper bottom surface, i.e. the bottom surface with a small diameter ofthe truncated-cone-shaped projection is connected with the plane end ofthe hemispherical projection, which can be molded integrally with a moldpreparation during production; the side wall of the bottom hollowelastic truncated-cone-shaped projection is set to be slightly thin andto have elasticity, and a plate with the hollow elastictruncated-cone-shaped projection and a mold for holding a plurality ofhemispherical projections can be separately used, and then the hollowelastic truncated-cone-shaped projections and the hemisphericalprojections can be bonded into a whole in one step by using the superglue, which is not specifically limited here. By using the structure,when the bullet hits the bulletproof structure, the arc-shaped surfacescan easily change the direction of the bullet, so that the impact forceis reduced; and the hollow elastic truncated-cone-shaped projection isdeformed, so that the direction of the bullet is easy to change, therebyreducing the impact force. In the actual production, the hollow elastictruncated-cone-shaped projection can also be set as a non-elastic hollowtruncated-cone-shaped projection, when the impact force of the bullet islarge, the hollow truncated-cone-shaped projection is first damaged, andthe hemispherical projection moves down along a damaged part, therebyfurther making the bullet change the direction easily.

As a preferred solution, referring to FIG. 7, the bottom surface of thehemispherical projection, which also is the top inner surface of thehollow elastic truncated-cone-shaped projection, is fixedly providedwith a protrusion part 13 extending towards the inner side of the hollowelastic truncated-cone-shaped projection, and the protrusion partdeviates from the spherical center of the hemispherical projection. Byadopting the structure, when the bullet vertically hits the center pointof the hemisphere, and when the elastic truncated-cone-shaped projection11 moves down, the protrusion part may first support the hemisphericalprojection on one side, the other side of the hemispherical projectioncontinues to move down so as to be supported by the protrusion part torotate, so that the movement direction of the bullet is changed, and theimpact force is reduced; if the hollow elastic truncated-cone-shapedprojection is fixed in a bonding way of super glue, the super glue canseal the bottom of a hollow part of the hollow elastictruncated-cone-shaped projection, when the elastic truncated-cone-shapedprojection 11 moves down, the compressed air can play a certainbuffering effect, after the movement direction of the bullet is changedand the direction of the impact force shifts, the buffering effect onlyaims at a component force of the impact force, and the buffering effectis better. As an arrangement way of the protrusion part, the protrusionparts can be arranged in a manner that the protrusion parts in thebulletproof bodies are alternately arranged on one side as shown in FIG.7, can also be all arranged on one side as shown in FIG. 8, and can alsobe arranged on the walls of the elastic truncated-cone-shapedprojections as shown in FIG. 9.
